Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine (a ball game machine) such as a pachinko gaming machine such as a so-called seven machine, feathers, or a right-handed machine, or a combination type gaming machine (arranged ball gaming machine).

  The pachinko gaming machine is configured to start the variation display of the lottery symbol when the game ball enters the starting port, and to start executing the big hit game when the lottery symbol is stopped and displayed in the big hit symbol. When the lottery symbol stop symbol is a specific jackpot symbol, the release frequency improving means for increasing the opening frequency of the start port is often activated after the jackpot game is over. In such a game machine, during the operation of the release frequency improving means, the lottery symbols are displayed using a shortened variation pattern that shortens the variation time of the lottery symbols. In general, the lottery symbols are displayed using a normal variation pattern that does not shorten the symbol variation time (see Patent Document 1).

JP 2004-105528 A

  However, in the configuration of the gaming machine described in Patent Document 1, the end of the operation of the release frequency improving means tends to be a trigger for stopping the game. In other words, during the operation of the release frequency improving means, the frequency of game balls entering the start port is higher than usual, and accordingly, the payout frequency of prize balls accompanying the entrance of game balls to the start port is also increased. Get higher. For this reason, during the operation of the release frequency improving means, it is possible to advance the game with almost no reduction of the player's ball. On the other hand, when the operation of the release frequency improving means is completed and the normal state is reached, the frequency of entering the game ball into the start port becomes lower than during the operation of the release frequency improving means, and accordingly, The payout frequency of prize balls accompanying the entry of the game balls becomes low. For this reason, in the state where the release frequency improving means is not operated, the player's balls are more likely to decrease than during the operation of the release frequency improving means, and for the player, a game ball used for the game is added (additional) Need to invest). For this reason, in the configuration of the conventional gaming machine as described in Patent Document 1 above, the end of the operation of the release frequency improving means tends to stop the game, and the player can play the game after the operation of the release frequency improving means ends. There is a problem that it is difficult to attract.

  In view of the above, an object of the present invention is to attract a player to a game even after the operation of the release frequency improving means is completed in a gaming machine including the release frequency improving means.

In order to achieve the above object, the gaming machine of the present invention provides:
A starter that can be switched between a normal state in which game balls are difficult to enter and an open state in which game balls are easy to enter;
A lottery symbol game executing means for stopping and displaying the lottery symbol in accordance with a predetermined variation pattern in the lottery symbol display section triggered by the game ball entering the start opening;
A jackpot game executing means for executing a predetermined jackpot game when the lottery symbol is stopped and displayed as a jackpot symbol in the lottery symbol display section;
An opening frequency improving means for improving the frequency at which the start port is opened after the jackpot game ends;
As a variation pattern of the lottery symbol, a normal variation pattern table for determining a normal variation pattern corresponding to a normal state in which the opening frequency of the start port is not improved by the opening frequency improving unit, and the opening frequency improving unit A shortened variation pattern table for determining a shortened variation pattern corresponding to an open frequency improvement state in which the opening frequency of the start port is improved, and a special variation pattern different from the normal variation pattern and the shortened variation pattern are determined. Fluctuation pattern table storage means for storing a special fluctuation pattern table for
Variation pattern determining means for determining a variation pattern of the lottery symbol using any of the plurality of variation pattern tables stored in the variation time table storage means;
A symbol variation effect execution means for executing a symbol variation effect corresponding to the variation display of the lottery symbol performed according to the variation pattern determined by the variation pattern determination means,
The variation pattern determining means determines a variation pattern of the lottery symbol using the shortened variation pattern table in the release frequency improvement state, and when the variation pattern determination unit shifts from the release frequency improvement state to the normal state, The variation pattern of the lottery symbol is determined using the special variation pattern table until the special variation period elapses, and after the elapse of the special variation period, the variation pattern of the lottery symbol is determined using the normal variation pattern table. It is characterized by doing.

  In the gaming machine of the present invention having such a feature, when shifting from the improved release frequency state to the normal state, the lottery pattern variation pattern is immediately shifted from the state set to the shortened variation pattern to the state set to the normal variation pattern. Instead, a transition is made to a state in which a special variation pattern different from the shortened variation pattern or the normal variation pattern corresponding to the gaming state (the operating state of the release frequency improving means) is set. When the special variation period corresponding to the game execution period when the lottery symbol variation pattern is set to the special variation pattern has elapsed, the lottery symbol variation pattern is changed from the special variation pattern to the normal variation pattern. Move to the set state. In other words, the state shifts to the setting state of the variation pattern corresponding to the gaming state (the operating state of the release frequency improving means).

  In this way, after the completion of the release frequency improving state, a lottery symbol variation pattern that differs from the lottery symbol variation pattern corresponding to the gaming state appears (a special variation period appears), and accordingly, according to the variation pattern. The symbol variation effect corresponding to the variation display of the lottery symbol that is displayed can also be a special symbol variation effect (special variation effect) different from the symbol variation effect corresponding to the gaming state. Then, by generating a special symbol variation effect (special variation effect), it is possible to make the player have some expectation, and this is an incentive to continue the game even after the open frequency improving state ends. As a result, it is possible to suppress the player from stopping the game as much as possible due to the end of the release frequency improvement state, and to attract the player to the game for a certain period even after the end of the release frequency improvement state, As a result, the operating rate of the gaming machine can be improved.

Further, the gaming machine of the present invention comprises a probability changing means for setting a jackpot probability that the lottery symbol is stopped and displayed in the jackpot symbol after the jackpot game is ended to a high probability higher than a normal probability,
The opening frequency improving means improves the frequency at which the start port is opened until the first predetermined period has elapsed after the jackpot game ends, and the probability varying means, after the jackpot game ends, The jackpot probability is set to a high probability until a second predetermined period that does not exceed the first predetermined period elapses.

  Thus, in the state where the opening frequency improvement period (first predetermined period) corresponding to the game execution period in the state where the opening frequency of the opening is improved (opening frequency improvement state), the jackpot probability is set to a high probability In a configuration that ends at the same time as the high probability period (second predetermined period) corresponding to the game execution period (high probability state or probability change state) or after the high probability period, when the release frequency improvement period ends, This means that the probability period has ended with certainty. For this reason, the end of the opening frequency improvement period tends to be a chance to stop the game. Therefore, in game machines whose release frequency improvement period ends at the same time as the high probability period or after the high probability period, special lottery symbols are used until the special fluctuation period elapses after the release frequency improvement state (opening frequency improvement period) ends. By variably displaying the variation pattern, it is possible to effectively suppress the player from stopping the game when the release frequency improvement state ends.

In addition, the gaming machine of the present invention displays the lottery symbol stopped at the jackpot symbol after the jackpot game started when the lottery symbol was stopped and displayed at the probability variable big bonus symbol among the jackpot symbols. A probability variation means for setting the jackpot probability to be set to a high probability higher than the normal probability,
The variation pattern determining means sets the jackpot probability to a high probability after the jackpot game started during the period when the jackpot probability is set to a high probability by the probability setting means. Only when the state is shifted to the release frequency improving state, the variation pattern of the lottery symbol is determined using the shortened variation pattern table in the release frequency improving state, and the state shifts from the release frequency improved state to the normal state. In such a case, the lottery pattern variation pattern is determined using the special variation pattern table until the special variation period elapses, and after the special variation period, the lottery determination is performed using the normal variation pattern table. It is characterized by determining a pattern variation pattern.

  In this way, after the end of the jackpot game started during the high probability period in which the jackpot probability is set to a high probability by the probability setting means, the probability changing means shifts to the release frequency improving state without operating, that is, In the high probability period, when the big hit game started after the big hit symbol is stopped and displayed as a big hit symbol, when the transition to the release frequency improved state (so-called short-time state) is made, When the game ends, the player recognizes that the advantageous period (a specific game period such as a high probability period or an opening frequency improvement period) for the player after the end of the big hit game has ended, and it is easy to start the game. For this reason, only after the end of the jackpot game that occurred during the high probability period, only when the release frequency improving means operates without the probability changing means being activated, the fixed period (special fluctuation) Period) to determine the lottery pattern variation pattern using the special variation pattern table, effectively suppressing the player from stopping the game due to the end of the release frequency improvement state, and the end of the release frequency improvement state Later, the player can be attracted to the game for a certain period of time.

  The gaming machine according to the present invention is characterized in that the special variation pattern table includes a plurality of the special patterns, and each of the special patterns has the same variation time of the lottery symbols.

  As a result, the total time of the special variation period (period in which the lottery symbol is variably displayed in the special variation pattern) in which the variation pattern of the lottery symbol is determined using the special variation pattern table is fixed. As a result, when designing the content of the effect (the content of the special variation effect) that is performed during the special variation period in which the lottery symbol is variably displayed in the special variation pattern, the design freedom can be increased. It is possible to create an effective production for attracting the player to the game.

  According to the above configuration of the present invention, in the gaming machine provided with the release frequency improving means, the player can be attracted to the game even after the operation of the release frequency improving means is completed.

In the game area 21, the central device 24, the normal symbol operating gate 27, the big winning device 33, the starting port 28, the left winning ports 34 and 35, the right winning ports 36 and 37, the first decorative member 50, and the second decorative member. A gaming device such as 60 is arranged. In addition, a number of obstacle nails are arranged in the game area 21 in consideration of the position balance with each gaming device.

  The central device (center accessory) 24 is disposed at a substantially central portion of the game area 21 and includes an effect display device 25. In the present embodiment, a large liquid crystal display device is used as the effect display device 25, and various effect displays are performed in the display area of the effect display device 25.

  The big winning device 33 is arranged below the central device 24 in the game area 21. The first decoration device 50 is arranged on the left side of the big prize device 33 in the game area 21, the second decoration device 60 is arranged on the right side of the big prize device 33 in the game area 21, and the decoration devices 50, 60 are so-called side. Make up decorations. Further, the first winning device 34 is integrated with the left winning holes 34 and 35, and the second winning device 60 is integrated with the right winning ports 36 and 37.

  The normal symbol operating gate 27 is provided on the left side of the central device 24. Inside the normal symbol operation gate 27, a normal symbol operation gate detection switch 27s (see FIG. 3) for detecting the passage of the game ball flowing down on the game board is provided. When the game ball passes through the normal symbol operating gate 27, the normal symbol starts to fluctuate.

  The start port 28 is provided below the central position of the central device 24. The start port 28 is a first start port provided on the upper side, in which two entrance ports formed with a game ball receiving port for receiving a game ball flowing down on the surface of the game board 20 are arranged side by side in the vertical direction. 28a and a second start port 28b provided on the lower side.

  The first starting port 28a is configured as a fixed starting port in which the size of the game ball receiving port does not change and the possibility of entering the game ball is constant, so that the game ball can always enter the game. It has become. On the other hand, the second start port 28b is a so-called tulip type and has a pair of wing pieces on the left and right, and the upper end gap between the pair of wing pieces serves as a game ball receiving port. The pair of wing pieces are each opened and closed by tilting in the left-right direction. With this opening and closing action, the second start port 28b is the size of the game ball receiving port of the pair of wing pieces. It is configured as a variable starter that changes. The second start port 28b is in an open state with a high probability of entering by opening a pair of blade pieces, and in a normal state with a low possibility of entering by closing a pair of blade pieces (incoming balls) Including an impossible closed state). When the normal symbol is stopped and displayed as a combination of symbols, the pair of wing pieces are opened to expand the game ball receiving port of the second start port 28b, and the second start port 28b is a normal electric accessory. Function as.

  Inside the start port 28, a start port entrance detection switch 28s (see FIG. 3) for detecting the entrance of a game ball, and a start port solenoid 28c (see FIG. 3) for operating a pair of wing pieces. Is provided. When the pair of wing pieces are opened to the left and right, the size of the game ball receiving port of the second start port 28b is enlarged from the normal time, and the second start port 28b has a possibility of entering a game ball. It becomes an open state that becomes larger. On the other hand, when the pair of wing pieces are erected, the size of the game ball receiving port of the second start port 28b is slightly larger than the diameter of the game ball (one game ball can pass). The second start port 28b is in a normal state (closed state) in which the possibility of entering a game ball is reduced (or entry is impossible). When a game ball enters one of the start ports 28a, 28b, a special symbol described later starts to fluctuate.

  The big prize device 33 is disposed below the start port 28. Here, the special winning device 33 includes a special winning opening 33a opened in a belt shape, an opening / closing plate 33b for opening / closing the special winning opening 33a, and a large winning opening solenoid 33c (for operating the opening / closing plate 33b). 3) and an incoming ball detection switch 33s (see FIG. 3) for detecting an incoming game ball.

  A left winning opening 34 and 35 and a right winning opening 36 and 37 are provided on the upper left side and the upper right side of the big winning device 33. Each of these winning openings is provided with a winning opening entering detection switch (not shown).

  The first decorative member 50 is provided with a plurality of LEDs, and a combination of these LEDs constitutes a normal symbol display portion 51, a general symbol hold display portion 52, and a special symbol hold display portion 53. Similarly, the second decorative member 60 is provided with a plurality of LEDs, and a special symbol display unit 61 is configured by a combination of these LEDs. The special symbol corresponds to the lottery symbol of the present invention, and the special symbol display unit 61 corresponds to the lottery symbol display unit of the present invention.

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operating gate 27, and after a predetermined time has passed, the normal symbol hits and stops display in the normal symbol display mode or the dismissed normal symbol display mode. Is done. When the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened according to a predetermined opening pattern. A plurality of opening patterns of the second start port 28b are set. When the opening time extension function for extending the opening time of the second start port 28b is not in operation (normal time), a short opening pattern in which a first opening time (for example, 1 to 2 seconds) is set is set and opened. When the time extension function is activated, a long-time opening pattern in which a second opening time (for example, 4 to 6 seconds) longer than the first opening time is set is set. The open time extension function will be described later.

  In the present embodiment, a random number for determining whether or not a normal symbol is provided is prepared. This random number for determining whether or not a normal symbol is used determines whether or not the second starting port 28b is activated when the game ball passes through the normal symbol operating gate 27. This is used to determine whether or not a normal symbol is appropriate. The normal symbol success / failure random number is set in advance with a hit value, and the normal symbol success / failure determination random number acquired at the timing when the game ball passes the normal symbol operation gate 27 matches the win value. Determined. When it is determined that the normal symbol is determined to be a win, the normal symbol that is stopped and displayed on the normal symbol display unit 51 is determined as the display mode of the normal symbol. On the other hand, when it is determined to be out (when the acquired normal symbol success / failure random number does not match the winning value), the normal symbol stopped and displayed in the normal symbol display unit 51 is determined as the display mode of the out of normal symbol. Is done.

  In this embodiment, when the opening time extending function for extending the opening time of the second start port 28b is activated, the normal symbol display section 51 displays a stop display compared to when the opening time extending function is not activated (normal time). There is a high possibility (probability) that a normal symbol to be hit will become a normal symbol display mode. That is, when the open time extension function is activated, the probability that the result of the normal symbol success / failure determination becomes a hit is higher than when the open time extension function is not activated (the probability variation function of the normal symbol success / failure determination). In the present embodiment, when the opening time extension function is activated, the fluctuation time of the normal symbol is shorter than when the opening time extension function is not activated (normal time) (normal figure fluctuation time reduction function). As a result, in this embodiment, when the open time extension function is activated, the actions of the “open time extension function”, the “normal figure fluctuation time reduction function”, and the “normal symbol success / failure probability change function” are combined. Thus, the opening frequency of the second start port 28b is improved as compared with the non-operating time (normal time) of the opening time extension function. In this way, the operation control of the “opening time extension function”, the “general symbol fluctuation time shortening function” and the “normal symbol success / failure probability fluctuation function” for improving the opening frequency of the second start port 28b is described below. This is performed by the control unit 200, and the main control unit 200 corresponds to the opening frequency improving means of the present invention.

  Here, normal symbol holding will be described. The normal symbol hold display section 52 displays the normal symbol hold number, and the number of game balls that have passed through the normal symbol operation gate 27 can be held up to the maximum hold number (four in this embodiment). Each time the next normal symbol win / fail determination is made and the normal symbol variation display is started, the number of unstarted times (the number of reservations) is consumed, and the number of normal symbol reservations is decreased by one. The general-purpose hold display unit 52 includes two LEDs, and can display the number of holds with an upper limit of four by combining turning off, lighting, and blinking of the two LEDs. Along with the holding of the normal symbol, a random number for determining whether or not the normal symbol is stored in a predetermined area of the RAM of the main control unit 200.

  The determination of whether or not the normal symbol is determined, the determination of the stop symbol of the normal symbol, the setting of the variation pattern of the normal symbol, the holding of the normal symbol and the holding of the normal symbol are performed by the main control unit 200 described later.

  Next, the special symbol will be described. The special symbol display unit 61 is composed of seven LEDs, and special symbols are displayed by these LEDs. Each LED constituting the special symbol display unit 61 can be turned on and off, and a plurality of special symbol display modes can be displayed by a combination of turning on and off the LEDs. Of the combinations of special symbols displayed by the seven LEDs, a specific combination is set as a big hit symbol, and a symbol other than the hit special symbol is set as a special symbol (out symbol). In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off. In the special symbol display unit 61, when the game ball enters the start port 28, the special symbol starts to change, and after a predetermined time has elapsed, the special symbol is stopped and displayed as a big hit symbol or a missed symbol. In this embodiment, a plurality of jackpot symbols are set, and specifically, “probable variation jackpot symbol” and “normal jackpot symbol” are set as will be described later.

  In the present embodiment, the first special symbol success / failure determination, which is acquired when a game ball enters the first start port 28a and is used for determining whether or not to execute the big hit game (special game), is performed. Random numbers for use and second special symbol success / failure determination, which is acquired when a game ball enters the second start port 28b and is used to determine whether or not to execute a big hit game (special game). A random number is provided. Furthermore, a first special symbol determining random number for determining the stop symbol of the first special symbol and a second special symbol determining random number for determining the stop symbol of the second special symbol are provided.

  As the game ball enters the first starting port 28a, the first special symbol success / failure determination random number and the first special symbol determination random number are acquired. One special symbol determination random number is stored in a predetermined area (first reserved storage area) of the RAM of the main control unit 200. Along with the game ball entering the second start port 28b, a second special symbol success / failure determination random number and a second special symbol determination random number are acquired, and a predetermined area (second) of the RAM of the main control unit 200 is obtained. Stored in a reserved storage area).

  Here, the holding of special symbols will be described. The first special symbol hold display unit 53 and the second special symbol hold display unit 54 are each composed of two LEDs, and the number of holds can be set up to 4 each by combining the turn-off, lighting, and blinking of the two LEDs. Can be displayed.

  The number of game balls that have entered the first start port 28a can be held until reaching the maximum number of reservations (four in this embodiment) as the number of first special symbol reservations. The first special symbol hold number is acquired every time a game ball enters the first start port 28a and is stored in a predetermined area (first hold storage area) of the RAM of the main control unit 200. This corresponds to the number (stored number) of special symbol random numbers (first special symbol success / failure determination random number, first special symbol determination random number). In the present embodiment, the first special symbol determination random number is acquired together with the first special symbol success / failure random number as the game ball enters the first starting port 28a, so the first special symbol hold number is This also corresponds to the number of stored random numbers for determining the first special symbol. The first special symbol hold count is digested and decreased by one each time the first special symbol determination is made and the first special symbol variation display is started.

  The number of game balls that have entered the second start port 28b can be held until reaching the maximum number of reservations (four in this embodiment) as the number of second special symbol reservations. The second special symbol hold number is acquired every time a game ball enters the second start port 28b and is stored in a predetermined area (second hold storage area) of the RAM of the main control unit 200. This corresponds to the number (stored number) of special symbol random numbers (second special symbol determination random number, second special symbol determination random number). In the present embodiment, the second special symbol determination random number is also acquired together with the second special symbol success / failure random number as the game ball enters the second starting port 28b. This also corresponds to the number of stored random numbers for determining the second special symbol. The second special symbol hold count is digested each time the second special symbol success / failure determination is performed and the variation display of the second special symbol is started, and decreases by one. The holding of the first and second special symbols and the holding digest are performed by the main control unit 200 described later.

  The special symbol success / failure determination random number is set with a hit value for success / failure determination, and the special symbol success / failure random number acquired at the timing when the game ball enters the first start port 28a or the second start port 28b. Is determined to be a big hit if it matches the hit value. The first special symbol success / failure determination is performed when the first special symbol starts variable display, and the second special symbol correctness determination is performed when the second special symbol starts variable display.

  When the first special symbol success / failure determination random number matches the winning value, it is determined to be a big hit, and the first special symbol stopped and displayed on the first special symbol display unit 61 becomes a big hit symbol (probability big hit symbol or normal big hit symbol). It is determined. If the random number for determining whether or not the first special symbol is correct does not match the winning value, the first special symbol displayed on the first special symbol display unit 61 is determined to be out of symbol.

  Similarly, when the second special symbol success / failure random number coincides with the winning value, it is determined as a big hit, and the second special symbol stopped and displayed on the second special symbol display unit 62 is the big hit symbol (probability big hit symbol or normal big hit) Design). If the random number for determining whether or not the second special symbol is coincident with the winning value, the second special symbol displayed on the second special symbol display unit 62 is determined to be out of symbol.

  The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The special symbol variation pattern is selected by lottery from a variation pattern table in which a plurality of variation patterns are stored when the special symbol success / failure determination is executed.

  A plurality of special symbol variation pattern tables are prepared, and each is selected and used according to the progress of the game. These multiple variation pattern tables include a “high probability shortened variation pattern table” selected in the high probability short-time gaming state in which all of the probability variation function, the variation time shortening function, and the open time extension function are operating, and the probability “Low probability shortening variation pattern table”, probability variation function, variation time shortening function selected in low probability short-time gaming state where the variation function is not activated, the variation time shortening function and the open time extension function are activated In addition, a “low probability normal variation pattern table” and a “special variation pattern table” that are selected in the low probability normal gaming state in which none of the open time extension functions are operating are included. `` Special variation pattern table '' is selected until the predetermined special variation period elapses when the transition time reduction function ends and the low probability short gaming state or low probability short gaming state transitions to the low probability normal gaming state Is done. These variation pattern tables are stored in the ROM of the main control unit 200. Accordingly, the ROM of the main control unit 200 corresponds to the variation pattern table storage means of the present invention.

  The high probability shortening variation pattern table, the low probability shortening variation pattern table, and the low probability normal variation pattern table are used corresponding to the gaming state (operation state of the probability variation function, the variation time shortening function, and the open time extension function), respectively. Thus, the types and appearance rates of the variation patterns included in each table also correspond to the gaming state (the operation state of the probability variation function, the variation time shortening function, and the open time extension function). On the other hand, the special variation pattern table is not a variation pattern table corresponding to the gaming state (operation state of the probability variation function, the variation time shortening function, the open time extension function), and the variation corresponding to the gaming state. Compared with pattern tables (high probability shortening variation pattern table, low probability shortening variation pattern table, low probability normal variation pattern table), the types and number of variation patterns included in the table, variation time specified by the variation pattern, etc. are different. ing. For this reason, in the special variation pattern, a variation pattern that cannot appear in the variation pattern table corresponding to the gaming state can appear, or a variation pattern appearance method different from the variation pattern table corresponding to the gaming state can be used. All of the special variation patterns defined in the special variation pattern table of the present embodiment have the same variation time (10 seconds in this embodiment), and thus the special variation having the same variation time (fixed time). When the special symbol is displayed in a variable manner according to the pattern, a special symbol variation effect (special variation effect) is performed by a later-described effect symbol change display (effect display by the effect display device 25) linked to the change display. It is configured. Details of the special symbol variation effect (special variation effect) will be described later.

  In addition, the gaming machine 1 according to the present embodiment is configured such that the second special symbol priority variation process is performed in which the variation display of the second special symbol is executed with priority over the variation display of the first special symbol. That is, when both the number of the first special symbol hold and the number of the second special symbol hold are 1 or more, the second special symbol starts to fluctuate preferentially from the first special symbol, and the hold of the second special symbol is stopped. Digested preferentially. Then, when the first special symbol hold count is 1 or more and the second special symbol hold count becomes zero, the variable display of the first special symbol is executed.

  It should be noted that first special symbol success / failure determination, second special symbol success / failure determination, special symbol variation mode (variation pattern) determination, special symbol stop symbol determination, first special symbol variation display and stop display, second special symbol Symbol variation display and stop display, and priority variation of the second special symbol are configured to be performed by the main control unit 200 described later. Therefore, the main control unit 200 corresponds to the lottery symbol game executing means and the variation pattern determining means of the present invention.

  Next, the jackpot game (special game) will be described. When the special symbol stopped and displayed on the special symbol display unit 61 is the above-mentioned jackpot symbol (when the result of the special symbol hit / fail determination is a big hit), the main control unit 200 is a jackpot that is relatively advantageous to the player. A game (special game) is started. The big hit game is started by setting the big hit game flag to ON, and the big winning device 33 is operated, in other words, the big winning opening 33a is opened and closed a plurality of times, so that the game balls to the big winning opening 33a are opened. It gives a player a profit (prize ball) for entering the ball. The big hit game is realized by repeatedly executing a big hit game process by the main control unit 200 described later, and the main control unit 200 corresponds to the big hit game execution means of the present invention.

  During the big hit game (during special game), the big prize device 33 is operated, and a predetermined number of prize balls (for example, 15 for one pitch) according to the number of game balls entered into the big prize opening 33a. Award balls). Specifically, the big winning opening / closing operation for continuously operating the big winning device 33 and switching the big winning opening 33a between the open state and the closed state is continuously performed a plurality of times by the start of the big hit game. With the start of the operation of the special winning device 33, the special winning opening 33a is opened. This open state is ended when a predetermined end condition is established, and the open special winning opening 33a is closed. As a predetermined ending condition, when the opening time of the grand prize opening 33a reaches a specified time (30 seconds in this embodiment) or the number of game balls that have entered the open big opening 33a is a predetermined number (this implementation) In the example, it is possible to reach 10).

  In the case where one round game is performed from the start to the end of the open state of the big winning opening 33a, the big hit game is ended when a predetermined number of round games are performed. In the grand prize winning device 33, after the special prize opening 33a has been opened, that is, after a predetermined time has elapsed since the big prize winning opening 33a is closed, the big prize winning opening 33a is again opened and the next round game starts. To do. The opening / closing operation of the grand prize winning port 33a in which one round game is from the opening start to the end of the big cash winning opening 33a is repeatedly continued until the predetermined maximum number of consecutive rounds is completed.

  In this embodiment, a plurality of maximum continuous round numbers are set. Specifically, two types of 3 rounds and 15 rounds are set as the maximum number of continuous rounds. When the main control unit 200 starts executing the big hit game, the main control unit 200 performs a random number lottery to determine the number of rounds of the big hit game.

  In the gaming machine of this embodiment, after the big hit game is finished, a specific game (so-called short-time game and probability variable game) in which the variable time shortening function, the open time extending function, and the probability varying function are activated is started. The variable time shortening function, the opening time extending function, and the probability varying function operate by setting the fluctuation shortening flag, the opening extension flag, and the probability changing flag to ON, respectively. The variable time shortening function and the open time extending function start simultaneously and end simultaneously. In the following description, when only one of the functions related to the operating state of the variable time shortening function and the open time extending function is described, the other function is also paired. For example, when it is described in the following description that “the variable time shortening function is operating”, this description can be interpreted as “the opening time extending function is also operating”. When it is described that “the function is operating”, this description can be understood as “the variable time reduction function is operating”.

  When the result of the special symbol success / failure determination is a normal jackpot (the special symbol stop symbol is a normal jackpot symbol), after the jackpot game is over, the variable time shortening function and the opening time extension for extending the opening time of the second start port 28b are extended. The function is activated and the short-time game is started. The short-time game (operation of the variable time reduction function and the opening time extension function) is realized by the control of the main control unit 200, which will be described later, and the variable time reduction function is a common technique for reducing the fluctuation time of a normal symbol. A variation time shortening function and a special diagram variation time shortening function for shortening the variation time of the special symbol are included. By the operation of the opening time extension function, the opening time of the second start port 28b is extended from the first opening time (for example, 1 to 2 seconds) to the second opening time (for example, 4 to 6 seconds). As a result, the frequency of entering the game ball into the second start port 28b is higher than that at normal time (when the opening extension function is not activated).

  If the result of the special symbol success / failure determination is a probable big hit (the stop symbol of the special symbol is a probable big hit symbol), after the big hit game ends, the probability variation function starts to operate, and the probable variable game is started. In this probability variation game, a probability variation function that changes (improves) the probability of special symbol success / failure determination, that is, the probability that the special symbol is stopped and displayed as a jackpot symbol is activated. This probability variation function is controlled by the main control unit 200 described later. It is realized by. For this reason, the main control unit 200 corresponds to the probability changing means of the present invention. Note that the probability variation function of this embodiment operates together with the variation time shortening function and the open time extension function.

  While the probability variation function is in operation, the probability of winning or failing determination increases, so that the probability that the result of the special symbol success / failure determination becomes a big hit is improved. Specifically, a normal probability success / failure determination table and a high probability success / failure determination table in which the hit value is increased from the normal probability success / failure determination table are prepared. During normal games (when the probability variation function is inactive), the normal probability determination table is used to determine whether or not, and during probability change games (when the probability variation function is in operation), a high probability determination table is used. Make a pass / fail decision.

  The fluctuation time shortening function, opening time extension function, and probability fluctuation function end their operations after the big hit game ends, until the next big hit game is started, or when the number of special symbol fluctuations reaches a predetermined number. . In the present embodiment, the probability variation function ends its operation when the number of variations of the special symbol reaches “20” without starting the next jackpot game after the jackpot game ends. As described above, the gaming machine according to the present embodiment is configured as a so-called ST machine that performs the limited probability variable game in which the operation period of the probability variation function is short and the start of the next special game is not secured (promise).

  Further, in this embodiment, depending on the operating state of the opening time extension function when the jackpot game is started (in other words, the operating state of the opening time extension function when the jackpot symbol is stopped and displayed), The operating period of the open time extension function is different. Specifically, if the opening time extension function was not activated when the big hit game was started, the fluctuation time was shortened when the number of special symbol fluctuations reached “20” after the big hit game ended. The function and the extended open time function are terminated. On the other hand, if the opening time extension function was activated when the big hit game was started, the fluctuation time shortening function and the opening time were reached when the number of changes in the special symbol reached “77” after the big hit game. The extension function is terminated.

  For this reason, if the open time extension function is not activated when the big hit game is started, the probability fluctuation function is used when the number of changes of the special symbol reaches “20 times” after the big hit game is finished. Then, each function of the variable time shortening function and the open time extending function is finished at the same time, and the high probability short gaming state is shifted to the low probability normal gaming state. On the other hand, if the opening time extension function was activated when the big hit game was started, the probability variation function was terminated when the special symbol variation number reached “20”, and the high probability short game state When the special symbol changes to “57 times” (= 77 times−20 times) after that, the fluctuation time shortening function and the opening time extension function are finished, and the low time is reduced. Transition from the short-probability gaming state to the low-probability normal gaming state.

  It should be noted that the game execution period until the operation termination condition of the probability variation function is satisfied (in this embodiment, until the number of variations of the special symbol after the end of the big hit game reaches “20 times”) This corresponds to the “second predetermined period” and the game execution period until the operation end condition of the variable time shortening function and the open time extension function is satisfied (in this embodiment, the number of times the special symbol fluctuates after the big hit game ends is “ “Until 20 times” or “77 times”) corresponds to the “first predetermined period” of the present invention.

  Next, the effect symbols displayed on the effect display device 25 will be described. In the display area of the effect display device 25, an effect symbol display unit 25a for displaying effect symbols is provided. The effect symbol of the effect symbol display unit 25a is displayed in conjunction with the change display and stop display of the first special symbol of the first special symbol display unit 61 or the second special symbol of the second special symbol display unit 62.

  The effect symbol display unit 25a is composed of three symbol display areas including a left symbol display area where a left symbol is displayed, a middle symbol display area where a middle symbol is displayed, and a right symbol display area where a right symbol is displayed. Yes. Each symbol display area has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction). Each symbol display area can display symbols consisting of “1” to “9”.

  When the first special symbol or the second special symbol is stopped and displayed in any of the symbols, the first symbol or the second special symbol is started. The special symbol or the second special symbol is stopped and displayed with a symbol corresponding to the stop symbol. In the production design, a combination of even symbols with the same three digits corresponds to a normal big hit symbol with a special symbol, a combination of odd symbols with the same three digits corresponds to a probabilistic jackpot symbol with a special symbol, and other symbol combinations are special. Corresponds to symbols that are out of design.

  The design pattern variation mode (variation pattern) and stop symbol determination are configured to be performed by the sub-control unit 260 based on a variation pattern designation command and a stop information designation command transmitted from the main control unit 200. Here, the variation pattern designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates the variation pattern of the special symbol. Specifically, the variation time of the special symbol and the presence / absence of the reach effect The contents of the production are shown. The main control unit 200 determines a variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol. Based on the special symbol variation pattern determined by the main control unit 200, the sub-control unit 260 determines the effect pattern of the effect symbol displayed on the effect symbol display unit 25a. Further, the stop information designation command transmitted from the main control unit 200 to the sub-control unit 260 indicates a special symbol stop symbol, and the main control unit 200 determines whether the special symbol is determined according to the result of the special symbol determination. A stop symbol is determined at random (by random number lottery). Then, based on the stop information designation command indicating the stop symbol of the special symbol determined by the main control unit 200, the sub control unit 260 determines the stop symbol of the effect symbol to be stopped and displayed on the effect symbol display unit 25a.

  In the present embodiment, during the period from the start of the display of the effect symbol to the stop display until the stop display, various effects such as a background change effect, a notice effect, and a reach effect are displayed on the display area of the effect display device 25 (the effect symbol display unit 25a). It is configured to perform the symbol variation effect. Also, in this embodiment, the production mode (probability production mode, time reduction production mode, normal mode) corresponding to the special symbol variation mode (high probability shortening variation mode, low probability shortening variation mode, low probability normal variation mode, special variation mode) Effect mode, special effect mode) is set, and mode effect display indicating the set effect mode is performed. In “mode display effect”, a background, a character, a character, or the like indicating the current variation mode can be displayed in the display area of the effect display device 25.

  Next, the operation of the gaming machine 1 of this embodiment will be described based on a flowchart. FIG. 4 is an example of a main job performed under the control of the main control unit 200. The main job shown in FIG. 4 is executed by the CPU 200b mounted on the main control board 200a in accordance with a program stored in a ROM (not shown) (an internal ROM of the CPU 200b or a ROM mounted on the main control board 200a). After the throwing-in process S100, the game start process S200, the normal symbol game process S300, the normal electric game game process S400, the special symbol game process S500, and the big hit game process S600 are repeatedly executed every time the timer is reset. . In the power-off generation process S50, when a power-off occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and so on, and when a system reset occurs, the process proceeds to the power-on process S100. It has become.

  The power-on process S100 is performed when the power is turned on and when the power is restored after the power is cut off. When the power is turned on, a RAM initialization process or the like is performed, and when the power is turned off, the game state is restored. The return setting is performed. In the game start process S200, detection of various switch states, update of various random numbers, prize ball payout control, and the like are performed.

  In the normal symbol game processing S300, first, whether or not the normal symbol is determined is determined, and the normal symbol display unit 51 (see FIG. 2) hits the normal symbol to stop display in the display mode of the normal symbol, or the display of the off-normal symbol is displayed. It is determined whether to stop display in the mode. Here, as described above, the probability of whether or not the normal symbol is correct in this embodiment is a probability of winning depending on the operating state of the opening time extension function (and the fluctuation time reduction function) that extends the opening time of the start port 28b. Are different, and the probability of hitting is higher when the open time extension function (and the variable time shortening function) is operating than when the open time extension function (and the variable time shortening function) is not operating.

  Next, when the result of determining whether or not the normal symbol is correct is obtained, the normal symbol fluctuation display time is set, and the normal symbol fluctuation display is started in accordance with the fluctuation display time. When the variable display time elapses, the normal symbol is stopped and displayed in the determined display mode, and when the normal symbol is hit and displayed in the normal symbol display mode, the operation of the normal electric accessory is started. (The second start port 28b is opened). In the normal symbol game process, the normal symbol variation display and stop display are performed as described above, and when the normal symbol is stopped and displayed in the normal symbol display mode, the second start port 28b is activated. I do. When the second start port 28b is actuated, the pair of blade pieces open to the left and right, and the second start port 28b is opened.

  In the ordinary electric accessory game process S400, it is determined whether or not the opening time for maintaining the second start port 28b in the open state has elapsed. If the open time has not elapsed, the second start port 28b is defined. It is determined whether or not a winning number has been won. When it is determined that the predetermined number of winnings has been won at the second starting port 28b in the open state, or when it is determined that the opening time of the second starting port 28b in the open state has elapsed, a pair of The blade piece is closed, and the second start port 28b is in a normal state (closed state).

  Next, the special symbol game process S500 will be described based on the flowcharts of FIGS. First, as shown in FIG. 5A, a start opening winning process is performed (S501). Here, the start opening winning process will be described based on the flowchart of FIG.

  First, it is determined whether or not the first start port 28a has been won (a game ball has entered) (S501a). If it is determined that the first start port 28a has not been won (S501a: NO). The process proceeds to S501d. On the other hand, if it is determined that the first start port 28a has been won (S501a: YES), it is determined whether or not the first special symbol hold number is less than 4 (S501b). As a result, when it is determined that the first special symbol reservation number is not less than 4 (4 or more) (S501b: NO), the process proceeds to S501d, and the first special symbol reservation number is less than 4. Is determined (S501b: YES), the first special symbol random number (first symbol success / failure determination information) is acquired and stored in a predetermined area of the RAM (S501c). The first special symbol random number includes a first special symbol determination random number, a first special symbol hit random number, a reach random number, and the like. Thereby, the 1st special symbol reservation number increases by one.

  Next, it is determined whether or not the second start port 28b has been won (S501d). If it is determined that the second start port 28b has not been won (S501d: NO). The start opening winning process is terminated. On the other hand, if it is determined that the second start port 28b has been won (S501d: YES), it is determined whether or not the second special symbol hold number is less than 4 (S501e). As a result, when it is determined that the second special symbol hold number is not less than 4 (4 or more) (S501e: NO), the start opening winning process is terminated, and the second special symbol hold number is less than 4. If it is determined that there is (S501e: YES), a second special symbol random number (second symbol success / failure determination information) is acquired and stored (S501f). The second special symbol random number includes a second special symbol determination random number, a second special symbol determination random number, a reach random number, and the like. Thereby, the number of second special symbol reservation increases by one.

  Next, returning to FIG. 5A, it is determined whether or not the big hit game is being played (whether or not the big hit game flag is ON) (S502). As a result, when it is determined that the big hit game is being played (the big hit game flag is ON) (S502: YES), the special symbol game process is terminated and the big hit game is not being played (the big hit game flag is OFF). ) (S502: NO), it is determined whether or not the special symbol (the first special symbol or the second special symbol) is changing (S503).

  As a result, when it is determined that the special symbol is changing (S503: YES), the process proceeds to S510 described later, and when it is determined that the special symbol is not changing (S503: NO). Then, it is determined whether or not it is during the special symbol stop display time (S504). Here, the stop display time of the special symbol is a time for determining the special symbol stopped and displayed. In this embodiment, the stop display time of the special symbol is “1 second”. If it is determined that it is during the special symbol stop display time (S504: YES), the process proceeds to S514 described later, and if it is determined that it is not during the special symbol stop display time (S504). : NO), it is determined whether or not the number of second special symbol hold is zero (S506). As a result, when it is determined that the number of second special symbol reservation is zero (S506: YES), it is determined whether or not the number of first special symbol reservation is zero (S507).

  And when it determines with the 1st special symbol holding | maintenance number being zero (S507: YES), a special symbol game process is complete | finished. On the other hand, when it is determined that the number of first special symbol hold is not zero (S507: NO), a first special symbol variation display process is performed (S508).

  On the other hand, if it is determined in S506 that the second special symbol hold count is not zero (S506: NO), a second special symbol variation display process is performed (S509). That is, if it is determined in the determination process of S506 that the second special symbol hold number is not zero (S506: NO), the first special symbol hold number is not zero (even if it is 1 or more). 2. The special symbol variation display process is executed. Thereby, the variation display of the second special symbol is performed in preference to the first special symbol, and the priority variation function of the second special symbol is realized by the determination processing in S506.

  Here, the first special symbol variation display process (S508) and the second special symbol variation display process (S509) will be described based on the flowchart of FIG. The first special symbol variation display process and the second special symbol variation display process are processes having the same contents except that the portions of the “first special symbol” and the “second special symbol” are different. The symbol is “first special symbol” in the first special symbol variation display process, and “second special symbol” in the second special symbol variation display process. Here, the first special symbol variation display process (S508) will be described, and the description of the second special symbol variation display process (S509) will be omitted.

  First, a random number for determining whether or not the first special symbol is stored in a predetermined area (first reserved storage area) of the RAM of the main control unit 200 (for determining whether or not the game ball has entered the first start port 28a) (Random number) is read (S508a), and the first special symbol determination is made (S508b). In the first special symbol success / failure determination, if the probability variation function is in operation (probability change game), the success / failure determination at the time of probability variation, that is, the state in which the determination result is a big hit (high probability state) When the decision is made and it is determined that the probability variation function is not operating (during normal game), it is determined whether or not it is a non-probability variation, that is, in a state where the probability that the determination result is a big hit (low probability state) Make a pass / fail decision.

  Next, it is determined whether or not the result of the first special symbol success / failure determination is a big hit (S508c). As a result, when it is determined that it is a big hit (S508c: YES), a big hit variation pattern table distribution process is performed (S508d), and when it is determined that it is not a big hit (S508c: YES), a deviation variation pattern. Table distribution processing is performed (S508g). Here, the big hit variation pattern table distribution processing and the outlier variation pattern table distribution processing will be described. Since these are the same contents, the “variation pattern table distribution processing” will be described based on the flowchart of FIG.

  First, it is determined whether or not the probability variation flag is ON (whether or not the high-probability short-time gaming state) (S550). As a result, if it is determined that the probability variation flag is set to ON (high probability, short gaming state) (S550: YES), a high probability shortening variation pattern table is set (S551). On the other hand, if it is determined that the probability variation flag is not set to ON (not a high-probability short-time gaming state) (S550: NO), whether or not the fluctuation shortening flag is set to ON (low-probability short-time gaming state) (S552).

  As a result, if it is determined that the fluctuation shortening flag is set to ON (low gaming state at low probability) (S552: YES), the low probability shortening fluctuation pattern table is set (S553). On the other hand, when it is determined that the variation shortening flag is not set to ON (not in the low probability short gaming state) (S552: NO), it is determined whether or not the special variation counter is greater than zero (S554). "Special variation counter" is a special variation pattern table that is selected as a special symbol variation pattern table and counts the period during which special symbols are subject to special variation. At the end of the big hit game, the opening time at the start of the big hit game It is set in the processing of S610g and S610i described later (see FIG. 13) according to the operating state of the extension function.

  As a result, if it is determined that the special variation counter is greater than zero (S554: YES), the special variation pattern table is set (S555). On the other hand, when it is determined that the special variation counter is zero (S554: NO), a low probability normal variation pattern table is set (S556).

  Each variation pattern table is prepared in advance with a table corresponding to the case where the result of the special symbol success / failure determination is a big hit and a table corresponding to the case where the special symbol is wrong, and each process of S551, S553, S555, and S556 is prepared. Then, a variation pattern table reflecting the result of the special symbol success / failure determination is set.

  When the variation pattern table distribution processing (S508d, S508g) is completed as described above, the processing proceeds to S508h in FIG. 7, and the variation pattern determination random number is acquired and stored in a predetermined area of the RAM of the main control unit 200. The symbol determination random number (the first special symbol determination random number acquired when the game ball enters the first start port 28a) is read (S508h).

  Next, a variation pattern and a stop symbol of the first special symbol are determined (S508i). As the first special symbol variation pattern, the first special symbol variation pattern determination random number acquired in S508h is used to select a specific variation pattern from the variation pattern table set in one of S508d and S508g. Further, the stop symbol of the first special symbol is determined to be one of the probable big hit symbol, the normal big hit symbol, or the off symbol using the symbol determining random number read in S508h.

  Next, according to the stop symbol and the variation pattern determined in S508i, the first special symbol display unit 61 starts the variation display of the first special symbol (S508j). A variation pattern designation command and a stop information designation command for the first special symbol are transmitted to the sub-control unit 260 (S508k). The variation pattern designation command is a command for designating the variation pattern of the first special symbol set in S508i, and the first special symbol information designation command is a command for designating the stop symbol of the first special symbol. When this variation pattern designation command and stop information designation command are transmitted to the sub-control unit 260, the symbol variation effect (effect) is controlled under the control of the sub-control unit 260 and the effect display control unit 280 that have received these commands (design variation start command). Symbol variation display) is started. Then, 1 is subtracted from the first special symbol reservation number (S508l). The above is the processing when starting the variable display of the first special symbol.

  Next, returning to FIG. 5A, if it is determined in S503 that the special symbol (the first special symbol or the second special symbol) is changing (S503: YES), the changing special symbol. It is determined whether or not the variable display time has elapsed (S510). As a result, if it is determined that the special symbol variation display time has not elapsed (S510: NO), it is determined that the special symbol game processing is terminated and the special symbol variation display time has elapsed. In this case (S510: YES), the special symbol variation display is stopped (S511), and a special symbol designating command indicating that the special symbol variation display is stopped is transmitted to the sub-control unit 260 (S512). A stop display time is set (S513).

  Next, it is determined whether or not the special symbol stop symbol display time has elapsed (S514). As a result, when it is determined that the special symbol stop symbol display time has not elapsed (S514: NO), the special symbol game processing is terminated and it is determined that the special symbol stop symbol display time has elapsed. If it is determined (S514: YES), it is determined whether or not the special symbol stop symbol is a big hit symbol (S515 in FIG. 5B). As a result, if it is determined that the stop symbol of the special symbol is a big hit symbol (S515: YES), the type of the big hit this time (normal big hit, probable big hit) and the current gaming state flag in the reference buffer at the time of the big hit end The state of (probability change flag, change shortening flag, release extension flag) is set (S516). Then, the special variation counter is set to zero (S517).

  Next, the jackpot game flag is set to ON (S518), and the number of rounds of the jackpot game is set to “3 rounds” or “15 rounds” (S519). Thereby, the big hit game is started.

  Next, it is determined whether or not the probability variation flag is ON (S520). If it is determined that the probability variation flag is ON (S520: YES), the probability variation flag is set to OFF (S521). Transition to processing. On the other hand, when it is determined that the probability variation flag is not ON (S520: NO), the process proceeds to S522 as it is.

  In the process of S522, it is determined whether or not the fluctuation shortening flag is ON. If it is determined that the fluctuation shortening flag is not ON (S522: NO), the special symbol game process is terminated as it is. On the other hand, when it is determined that the fluctuation shortening flag is ON (S522: YES), the fluctuation shortening flag is set to OFF (S523), and the release extension flag is set to OFF (S524). Thereby, along with the start of the big hit game, all of the probability variation function, the variation time shortening function, and the open time extension function are stopped.

  Next, in the determination process of S515, when it is determined that the special symbol stop symbol is not a big hit symbol (S515: NO), a probability variation monitoring process is performed (S525). Here, the probability variation monitoring process will be described based on the flowchart of FIG.

  First, it is determined whether or not the probability variation flag is set to ON (whether or not the probability variation function is activated) (S525a). As a result, when it is determined that the probability variation flag is not set to ON (the probability variation function is not activated) (S525a: NO), the probability variation monitoring process is terminated. On the other hand, when it is determined that the probability variation flag is set to ON (the probability variation function is activated) (S525a: YES), the probability variation counter is decremented by 1 (S525b). The “probability variation counter” counts the operation period (high probability period) of the probability variation function, and is set in the process of S610d described later (see FIG. 13) at the end of the big hit game.

  Next, it is determined whether or not the probability variation counter is zero (S525c). As a result, when it is determined that the probability variation counter is not zero (S525c: NO), the probability variation monitoring process is terminated and the operation of the probability variation function is continued. On the other hand, if it is determined that the probability variation counter is zero (S525c: YES), the probability variation flag is set to OFF (S525d). As a result, the operation of the probability variation function ends.

  Next, returning to FIG. 5B, the fluctuation shortening monitoring process is performed (S526). Here, the fluctuation shortening monitoring process will be described based on the flowchart of FIG.

  First, it is determined whether or not the fluctuation shortening flag is set to ON (whether or not the fluctuation time shortening function is activated) (S526a). As a result, when it is determined that the fluctuation shortening flag is not set to ON (the fluctuation time shortening function is not activated) (S526a: NO), the fluctuation shortening monitoring process is terminated. On the other hand, if it is determined that the variation shortening flag is set to ON (the variation time shortening function is activated) (S526a: YES), the variation shortening counter is decremented by 1 (S526b). “Variation shortening counter” is for counting the operation period (opening frequency improvement period) of the fluctuation time shortening function and the opening time extension function, and the operation of the opening time extension function at the start of the big hit game at the end of the big hit game It is set in the processing of S610f and S610h described later (see FIG. 13) according to the state.

  Next, it is determined whether or not the fluctuation shortening counter is zero (S526c). As a result, when it is determined that the fluctuation shortening counter is not zero (S526c: NO), the fluctuation shortening monitoring process is terminated, and the operation of the fluctuation time shortening function and the open time extending function is continued. On the other hand, when it is determined that the fluctuation shortening counter is zero (S526c: YES), the fluctuation shortening flag is set to OFF (S526d), and the release extension flag is set to OFF (S526d). Thereby, the operation of the variable time shortening function and the open time extending function is completed.

  Next, returning to FIG. 5B, special fluctuation monitoring processing is performed (S527). Here, the special variation monitoring process will be described based on the flowchart of FIG.

  First, it is determined whether or not the special variation counter is greater than zero (S527a). As a result, when it is determined that the special fluctuation counter is zero (S527a: NO), the special fluctuation monitoring process is terminated. On the other hand, when it is determined that the special variation counter is greater than zero (S527a: YES), the special variation counter is decremented by 1 (S527b). At this time, if the special variation counter is larger than zero, the special variation of the special symbol is continued, and if the special variation counter becomes zero, the special variation of the special symbol is finished.

  Next, returning to FIG. 5B, it is determined whether or not the change mode of the special symbol has been changed (S528). The special symbol change mode is changed when the special symbol change ends when the high probability reduced change mode is changed to the low probability reduced change mode (see S525d in FIG. 9). (See S526d and S526e in FIG. 10), or transition from the special fluctuation mode to the low-probability normal fluctuation mode (when the special fluctuation counter becomes zero by the process of S527b in FIG. 11). .

  As a result, when it is determined that the change mode has not been changed (S528: NO), the special symbol game process is terminated. On the other hand, if it is determined that the change mode has been changed (S528: YES), a mode designation command indicating the changed change mode is transmitted to the sub-control unit 260 (S529).

  Next, the jackpot game process S600 will be described based on the flowchart of FIG. First, it is determined whether or not the jackpot game is being played (whether or not the jackpot game flag is ON) (S601). As a result, if it is determined that the jackpot game is not being played (the jackpot game flag is OFF) (S601: NO), the special symbol game process is terminated and the jackpot game is being played (the jackpot game flag is ON). ) (S601: YES), it is determined whether or not the special winning opening 33a is being opened (S602). As a result, when it is determined that the special winning opening 33a is being opened (S602: YES), it is determined whether or not the opening time of the special winning opening 33a has elapsed (S603), and the special winning opening 33a is determined. When it is determined that the opening time has not elapsed (S603: NO), it is determined whether or not the specified winning number 33a has been won (whether or not the specified number of game balls have entered). (S604).

  As a result, if it is determined that the prescribed number of winnings has not been won in the big winning opening 33a (S604: NO), the jackpot game processing is terminated and the prescribed winning number has been won in the big winning opening 33a. When it is determined (S604: YES) or when it is determined that the opening time of the special winning opening 33a has elapsed (S603: YES), the special winning opening 33a is closed (S605).

  If it is determined in S602 that the special winning opening 33a is not being opened (S602: NO), it is determined whether or not the big hit game ending condition is satisfied (S606). The determination process of S606 determines whether or not the number of rounds of the jackpot game has reached the number of rounds (15 rounds or 3 rounds) set at the start of the jackpot game.

  As a result, when it is determined that the big hit game ending condition is not satisfied (S606: NO), it is determined whether or not the closing time (interval time) of the big winning opening 33a has passed (S607), When it is determined that the closing time of the big prize opening 33a has not elapsed (S607: NO), the big hit game process is terminated, and it is determined that the closing time of the big prize opening 33a has elapsed. (S607: YES), the special winning opening 33a is opened (S608).

  If it is determined in S606 that the big hit game end condition is satisfied (S606: YES), the big hit game end process is performed (S610). Here, the big hit game end process will be described based on the flowchart of FIG.

  In the big hit game end process, first, the big hit game flag is set to OFF (S610a). Next, it is determined whether or not the jackpot symbol is a probability variation jackpot symbol (whether or not it is a probability variation jackpot game) (S610b). Whether or not the big hit symbol is a probabilistic big hit symbol may be determined by referring to the big hit game end reference buffer set at the start of the big hit game in the above-described processing of S516 (FIG. 5B).

  As a result, when it is determined that the symbol is not a probable big hit symbol (usually a big hit symbol) (S610b: NO), the process proceeds to S610e. On the other hand, if it is determined that the symbol is a probable big hit symbol (S610b: YES), the probability variation flag is set to ON (S610c), thereby starting the operation of the probability variation function (becomes a high probability state). Then, the probability variation counter is set to “20” (S610d). Thereby, the operation period of the probability variation function (high probability period: second predetermined period) is set until the number of times of variation of the special symbol reaches 20 after the big hit game is finished.

  Next, it is determined whether or not the release extension flag when the jackpot symbol is stopped is ON (whether or not the release time extension function was activated at the start of the jackpot game) (S610e). The state of the release extension flag when the big hit symbol is stopped and displayed may be referred to the big hit game end reference buffer set at the start of the big hit game in the above-described processing of S516 (FIG. 5B).

  As a result, when it is determined that the release extension flag is not ON at the time of the big hit symbol stop display (the release time extension function has not been activated at the start of the big hit game) (S610e: NO), the fluctuation shortening counter is set. It is set to “20” (S610f), and the special variation counter is set to “40” (S610g). On the other hand, when it is determined that the release extension flag is ON (the opening time extension function was activated at the time of the big hit game start) when the big hit symbol is stopped (S610e: YES), the fluctuation reduction counter is set to “77”. ”(S610h) and the special variation counter is set to“ 97 ”(S610i).

  If the opening time extension function is not activated at the time of starting the big hit game (S610e: NO), the fluctuation shortening counter is set to “20” which is the same number as the probability changing counter. When the number of changes reaches 20, the probability change function, the change time shortening function, and the open time extension function end simultaneously. For this reason, the variation mode of the special symbol shifts from the high probability shortening variation mode to the special variation mode without going through the low probability shortening variation mode.

  On the other hand, when the opening time extension function is activated at the time of starting the big hit game (S610e: YES), the variation shortening counter is set to “77” which is “57” more than “20” set in the probability variation counter. Therefore, after the end of the jackpot game, when the number of changes of the special symbol reaches 20 times, the probability variation function finishes operating first, and then when the number of changes of the special symbol reaches 57 times (the jackpot When the number of special symbol variations after the game ends reaches 77), the variation time shortening function and the opening time extension function are simultaneously terminated. For this reason, in this embodiment, the variation mode of the special symbol shifts from the high probability shortening variation mode to the special variation mode via the low probability shortening variation mode.

  The special variation counter is set to “97” when the opening time extension function is activated at the start of the big hit game, and “40” when the opening time extension function is not activated at the time of the big hit game. Set to That is, the special variation counter is set to a value that is “20” more than the variation shortening counter both when the opening time extension function is activated at the time of starting the big hit game and when it is not activated. For this reason, the special variation mode is continued from the point in time when the variation time shortening function and the open time extension function are completed until the number of variations of the special symbol reaches 20. Then, when the special variation mode ends, the mode shifts to the low probability normal variation mode.

  Next, when the setting of each counter (probability variation counter, variation shortening counter, special variation counter) is completed, the variation shortening flag is set to ON (S610j), and the open extension flag is set to ON (S610k). As a result, the operation of the variable time shortening function and the open time extending function starts. Then, the mode designation command is transmitted to the sub-control unit 260 (S610l). The special symbol variation mode at the end of the big hit is either the high probability shortening variation mode or the low probability shortening variation mode. Therefore, when the probability variation flag is ON, the mode indicating the high probability shortening variation mode. When the specified command is transmitted and the probability variation flag is OFF, a mode specifying command indicating that the low probability shortening variation mode is transmitted.

  Next, the effect mode setting process performed by the sub-control unit 260 will be described based on the flowchart of FIG. FIG. 14 is an example of an effect mode setting process performed under the control of the sub-control unit 260, and is executed as a subroutine of a main routine (not shown). The effect mode setting process shown in FIG. 14 is executed by the CPU 260b mounted on the sub control board 260a according to a program stored in a ROM (not shown) (an internal ROM of the CPU 260b or a ROM mounted on the sub control board 260a).

  First, it is determined whether or not the mode designation command transmitted by the main control unit 200 has been received in the process of S529 (FIG. 5B) or the process of S610l (FIG. 13) (S700). As a result, when it is determined that the mode designation command has not been received (S700: NO), the effect mode setting process is terminated. On the other hand, if it is determined that the mode designation command has been received (S700: YES), it is determined whether or not the variation mode designated by the mode designation command is the high probability reduced variation mode (S701).

  As a result, when it is determined that the mode is the high probability shortening variation mode (S701: YES), the production mode is set to the probability variation production mode (S702). On the other hand, when it is determined that the variation mode designated by the mode designation command is not the high probability shortening variation mode (S701: NO), it is determined whether the variation mode is the low probability shortening variation mode (S703). .

  As a result, when it is determined that the low-probability shortening variation mode is set (S703: YES), the effect mode is set to the time-saving effect mode (S704). On the other hand, when it is determined that the variation mode designated by the mode designation command is not the low probability shortening variation mode (S703: NO), it is determined whether or not the variation mode is the special variation mode (S705).

  As a result, when it is determined that the special variation mode is set (S705: YES), the production mode is set to the special variation production mode (S706). On the other hand, when it is determined that the variation mode designated by the mode designation command is not the special variation mode (S705: NO), the effect mode is set to the normal effect mode (S707).

  Next, mode effect display is executed using the display area of the effect display device 25 based on the set effect mode (S708). As described above, the “mode effect display” can display a background, a character, a character, or the like indicating the current effect mode in the display area of the effect display device 25. For example, the background can be red in the probability effect mode, the background can be blue in the time reduction mode, and the background can be green in the normal mode. In the special effect mode, for example, a movie using a character can be played (moving images are reproduced). In the special variation pattern table, since the variation times of all the variation patterns are the same (10 seconds in this embodiment), the length of the period during which the special symbols are variably displayed according to the special variation pattern is a fixed time (200 seconds = 10 seconds). × 20 times). For this reason, during the mode display effect in the special effect mode, every time a variation pattern designation command for designating the special variation pattern transmitted from the main control unit 200 is received (variable display of the special symbol based on the special variation pattern is started. For example, a special symbol variation effect (special variation effect) is performed by playing a movie (for example, playing a moving image) having a content such as a battle between an ally character and an enemy character. If the special symbol is stopped and displayed as a winning symbol during the special performance mode, the winning movie of the content that the teammate character wins is played back. Play a movie for falling off. These movies (moving images) are prepared in advance based on the variation time defined by the special variation pattern, and are stored in an image ROM (not shown) provided on the effect display control board 280.

  The special symbol variation effect (special variation effect) is not limited to the above-described form (reproduction of a moving image representing a battle scene of a character), and various forms can be employed. For example, the symbol variation effect corresponding to the variation display of the special symbol performed according to the special variation pattern may always include the reach effect. In other words, an effect that is unlikely or cannot occur when using the variation pattern table corresponding to the gaming state may be configured as a special symbol variation effect (special variation effect).

  Next, the symbol variation effect process performed by the sub-control unit 260 will be described. The symbol variation effect process is based on the symbol variation start command (variation pattern designation command and stop information designation command) transmitted from the main control unit 200. This is a process for performing the effect symbol variation display on the display device 25. Specifically, when the variation pattern designation command transmitted from the main control unit 200 designates the variation pattern defined by the “high probability shortening variation pattern table”, the symbol variation rendering (corresponding to the probability variation rendering mode ( When executing the probability variation game symbol variation effect) and specifying the variation pattern specified in the “low probability shortening variation pattern table”, the symbol variation effect corresponding to the time reduction effect mode (time variation game symbol variation effect) When executing and designating the variation pattern specified in the “low probability normal variation pattern table”, the symbol variation effect corresponding to the normal performance mode (ordinary game symbol variation effect) is executed, and the “special variation pattern table” is executed. In the case of designating the variation pattern defined by “”, the symbol variation effect (special variation effect) corresponding to the special variation effect mode is executed. Hereinafter, the symbol variation effect process will be described based on the flowchart of FIG.

  FIG. 15 is an example of a symbol variation effect process performed under the control of the sub-control unit 260, and is executed as a subroutine of a main routine (not shown). The symbol variation effect process shown in FIG. 15 is executed by the CPU 260b mounted on the sub control board 260a in accordance with a program stored in a ROM (not shown) (an internal ROM of the CPU 260b or a ROM mounted on the sub control board 260a).

  First, in the processing of S508k and S509k (see FIG. 7), it is determined whether or not a symbol variation start command (a variation pattern designation command and a stop information designation command) transmitted from the main control unit 200 has been received (S800). ). As a result, if it is determined that the symbol variation start command has not been received (S800: NO), the process proceeds to S805 described later. On the other hand, if it is determined that the symbol variation start command has been received (S800: YES), it is determined whether the result of the special symbol success / failure determination is a big hit (S801). The result of the special symbol success / failure determination can be determined based on the type of variation pattern designated by the variation pattern designation command or the type of stop symbol of the special symbol designated by the stop information designation command.

  As a result, when it is determined that the result of the special symbol success / failure determination is a big hit (S801: YES), a big hit effect pattern and a stop symbol (big hit symbol) are selected and set (S802). On the other hand, when it is determined that the result of the special symbol success / failure determination is not a big hit (S801: NO), the effect pattern when the effect symbol is out and the stop symbol (out symbol) are selected and set (S803). Then, the variation display of the effect symbol is started in the display area of the effect display device 25, and the symbol variation effect is started (S804).

  Next, it is determined whether or not a symbol stop command transmitted from the main control unit 200 has been received in the process of S512 (see FIG. 5A) (S805). As a result, when it is determined that the symbol stop command has not been received (S805: NO), the symbol variation effect process is terminated, and when it is determined that the symbol stop command has been received (S805: YES), the effect symbol that is variably displayed in the display area of the effect display device 25 is stopped and displayed at the stop symbol set in S802 or S803, and the symbol variation effect is ended (S806).

  Here, the correspondence between the processing shown in the flowcharts of FIGS. 5 to 15 and each means of the present invention will be described. The processing of S503 to S511 (FIG. 5 (a), FIG. 7) is the lottery of the present invention. Corresponding to the symbol game executing means, the processing of S518, S601 to S610 (FIG. 5B, FIG. 12) corresponds to the big hit game executing means, and the processing of S610h, S610h, 610k (FIG. 13) is the opening frequency improving means. , S508d, S509d, S508g, and S509g (FIGS. 7 and 8) correspond to the variation pattern determining means, S610c and S610d (FIG. 13) correspond to the probability variation means, and S800 to S806. The process (FIG. 15) corresponds to the symbol variation effect executing means.

  In the present embodiment described above, when the variation pattern of the special symbol is determined, a shortened variation pattern table (high probability shortened variation pattern table, low probability shortened variation pattern table) is used while the release time extension function is in operation. The special variation pattern table is used between the time extension function operation and the special symbol variation display for the specified number of times (until the special variation period elapses). Usually, a variation pattern table is used. For this reason, when the opening time extension function ends, the special symbol variation pattern does not immediately shift from the shortened variation pattern corresponding to the gaming state to the normal variation pattern, but is set to a special variation pattern that does not correspond to the gaming state. After a period of time (special variation period) has elapsed, the normal variation pattern is entered.

  In this way, after the activation of the open time extension function, a special variation pattern that does not correspond to the game state is caused to appear, and the symbol variation effect corresponding to the variation display of the special symbol performed according to the special variation pattern is displayed as `` special symbol "Variation production (special variation production)". Then, by generating a special symbol variation effect (special variation effect), the player can have some expectation. As a result, it is possible to suppress the player from stopping the game as much as triggered by the operation end of the opening time extension function as much as possible, and to attract the player to the game for a certain period even after the operation of the opening time extension function ends. As a result, the operating rate of the gaming machine can be improved.

  In addition, a special variation pattern that does not correspond to the operation of the open time extension function until it shifts from the shortened variation pattern corresponding to the operation of the open time extension function to the normal variation pattern corresponding to the non-operation of the open time extension function. By sandwiching, it is possible to create a “connection period” from the shortened variation pattern to the transition to the normal variation pattern. This makes it difficult to give the player an impression that the transition from the operating state of the opening time extension function to the non-operating state of the opening time extension function is instantaneously performed.

  In the present embodiment, since the variation time of the variation pattern included in the special variation pattern table is set to a fixed time (constant), the total time during which the special symbol varies specially is fixed. As a result, the degree of freedom of design can be expanded when designing the contents of the effects performed during the period in which the special symbol is specially changed.

  In addition, the gaming machine 1 according to the present embodiment is configured to perform a limited probability variation game in which the probability variation function ends in a relatively short period as described above, and in particular, the probability variation function is simultaneous with or released from the open time extension function. In the case of a configuration in which the operation ends before the time extension function, the operation end of the release time extension function tends to trigger the game. For this reason, in the gaming machine that performs the limited probability change game as in the present embodiment, it is particularly effective to perform the special variation of the special symbol until the predetermined period (special variation period) elapses after the operation of the open time extension function ends. is there.

(Second embodiment)
Next, a second embodiment of the present invention will be described. In the second embodiment, only the parts different from the first embodiment will be described.

  FIG. 16 is a flowchart showing the latter half of the special symbol game process of the second embodiment, and corresponds to FIG. 5B of the first embodiment.

  As shown in FIG. 16, in the second embodiment, the big hit game with 3 rounds is not set, and in the round number setting process of S519, the round number of the big hit game is set to only 15 rounds. . Further, in the second embodiment, since the probability variation function is configured to operate until the next special game state occurs after the special game state ends, the probability change monitoring process of S525 in FIG. Not provided.

  FIG. 17 is a flowchart showing the big hit game ending process of the second embodiment, and corresponds to FIG. 13 of the first embodiment. In the second embodiment, since the probability variation function is configured to operate until the next special game state occurs after the special game state ends, the probability variation counter setting process in S610d and the determination process in S610e in FIG. Is not provided.

  In the second embodiment, when it is determined that the big hit symbol is the probability variation big hit symbol (S610b: YES), the probability variation flag is set to ON (S610c), and the fluctuation shortening counter is set to “10,000”. (S610f). On the other hand, when it is determined that the big hit symbol is not a probable big hit symbol (usually a big hit symbol) (S610b: NO), the fluctuation shortening counter is set to “100” (S610h), and the special fluctuation counter is “120”. (S610i). As a result, in the case of a probability variation game, the number of changes in the special symbol reaches 10,000 (substantially until the next big hit game starts), and in the case of a short-time game, the number of changes in the special symbol reaches 100. Until it reaches, the variable time reduction function and the open time extension function are activated.

  Next, the fluctuation shortening flag is set to ON (S610j), the open extension flag is set to ON (S610k), and a mode designation command is transmitted to the sub-control unit 260 (S610l).

  In the second embodiment described above, the short-time game is started after the big hit game is finished, and when the number of executions of the special symbol variable display in the short game at that time reaches “100 times”, the special symbol “20 times” from there. Until the change display is performed, the special symbol change display based on the special change pattern is performed. In other words, the special variation effect is performed from the end of the short-time game until the “20 times” special symbol variation display is performed. As in the second embodiment, after the jackpot game is over, the next jackpot game is continued until the next jackpot game is started, and in the game machine in which the short-time game is continued for a predetermined period after the jackpot game is finished, the open time extension function is activated. When the game ends (when the short-time game ends), the special symbol variation pattern is not set to the normal variation pattern immediately from the shortened variation pattern corresponding to the gaming state, but to the special variation pattern not corresponding to the gaming state. The effect similar to that of the first embodiment can be obtained by shifting to the normal fluctuation pattern after the period (special fluctuation period) elapses. In other words, it is possible to prevent the player from stopping the game as much as possible by the end of the opening time extension function (end of the short-time game), and for a certain period after the end of the opening time extension function (end of the short-time game) The player can be attracted to the game.

(Third embodiment)
Next, a third embodiment of the present invention will be described. In the third embodiment, only parts different from the above embodiments will be described.

  FIG. 18 is a flowchart showing the big hit game ending process of the third embodiment, and corresponds to FIG. 13 of the first embodiment.

  As shown in FIG. 18, in the third embodiment, when it is determined that the big hit symbol that triggered the start of the big hit game to be terminated this time is the probability variation big hit symbol (S610b: YES), the probability variation flag is turned ON. (S610c), and the fluctuation shortening counter is set to “10,000” (S610f). On the other hand, if it is determined that the jackpot symbol is not a probability variation jackpot symbol (usually a jackpot symbol) (S610b: NO), first, the fluctuation shortening counter is set to “100” (S610h). Next, it is determined whether or not the probability change flag is ON (whether or not the jackpot game that is ended this time is started during the probability change game) when the jackpot symbol that is the trigger for starting the jackpot game that is ended this time is displayed (S610m). ). The state of the probability variation flag when the big hit symbol is stopped and displayed may be referred to the big hit game end reference buffer set at the start of the big hit game in the above-described processing of S516 (FIG. 5B).

  As a result, if it is determined that the probability variation flag is ON when the big hit symbol is stopped (S610m: YES), the special variation counter is set to "120" (S610i). On the other hand, if it is determined that the probability variation flag is not ON when the big hit symbol is stopped (S610m: NO), the process proceeds to S610j without setting the special variation counter.

  Next, the fluctuation shortening flag is set to ON (S610j), the open extension flag is set to ON (S610k), and a mode designation command is transmitted to the sub-control unit 260 (S610l).

  When a big hit game is generated during a probability change game, the probability variation function does not operate after the big hit game ends, and the transition to the short time game is made. And since the player recognizes that a series of specific games consisting of short-time games has ended, this tends to stop the game. For this reason, as in the third embodiment, a special variation counter is set only when transitioning to a time-saving game after the end of the normal big hit game that occurred during the probability-changing game. After the end of the special symbol, the special symbol can be changed. As a result, the end of the short-time game started after the probability change game (end of the operation of the opening time extension function) is used as a trigger to suppress the player from stopping the game as much as possible, and even after the operation of the opening time extension function ends, The player can be attracted to the game for a certain period of time.
